To all whom it may concern:

-Be it known that I, FREDERICK HAOH- MANN, a citizen of theUnitedstates, and.

reference being had to accompanying draw- I ings, forming a part.thereof.

My invention relates to certain new and useful improvements in bottleclosures and has for its primary object a removable closure for milkbottles, the same being provided with securing means adapted to beinserted on the inside of themouth ,of a bottle, so that the exterior ofthe bottle mouth is free at all times to bekept in a clean and sanitarycondition.

In the drawings: v Figure 1 is a side-elevation of a, portion of abottle with parts broken away, showing my invention applied thereto.

Fig. 2 is a cross-sectional view of the same.

Fig. 3 is an inverted perspective view of the cap and securing member.

Fig. 4 is a plan View of the securing mem her before being bent intoshape for use.

Referring to the drawings, 4: indicates a fragment of a bottle neckhaving the usual mouth edge or rim 5. 6 indicates the lid of my improvedclosure, which is stamped from a piece of sheet metal and is provided onits underneath surface with a groove 7,.

10 indicates the securing member for my l closure, which is formed of aresilient. or

elastic piece of metal, which is adapted to be bent inwardly forinsertion on the inside of the bottle neck and by expansive force willfirmly secure the closure in place on the bottle neck. Secured to theI'eS'llll'lt;

or elastic band or securing member 10 is an arm 11, which has ahorizontal portion 12 which seats or fits in a depression 13 formed inthe lid' 6, so as to permit the lid to snugly arm secured to saidcircular band and lying 4 seat on the top edge of the bottle neck.

Formed on one end of the vertical de- Having v fully what I claim is:

or projections 15 which are adapted to be inserted in theperforated ears9 carried by the handle 8. Mounted on these projections or studs 15 arecoil springs 16 one on each side of the arm, the same being connectedtogether by a loop 17, which is seated beneath the arm 11.

The free ends 18 of the springs 16 rest beneath the handle 8. By meansof these springs, the lid is spring held on the top of the bottle neck.

In order to apply my closure to a bottle, the resilient member 10 is putunder compression and forced on the inside ofthe bottle 'neck and, aspreviously stated, is held in position by the expansive force of themember 10.

In order to open or lift the lid, all that is necessary is a slightpressure against 'the outside of the handle 8. By locating the securingmember 10 on the inside of the Patented Oct. 21, 1919.
